Hello, I'm new to the forum. I recently acquired a '68 SS with front disc brakes and was considering upgrading the rear drums to disc. I was hoping to get feedback from any one thats made the upgrade and if it's an improvment to what degree, Also, what kit does the best job as I've seen 3-4 on the market. I'm also considering changing out the "14x6 rims to "15x7 - are there any problems going with the 15's front & rear? What tire sizes would you recommend 225 or 235? Is therd enough clearance in front for these?

I run 15X8s on my '68. I have 295s in the back and 265s in the front. The fronts rub a bit. But I think with another 1/2" of back spacing, it wouldn't. So, 225 or 235 should be fine.

As far as the brakes, I'm sure some people on here can help you out. I can't. But I'd like to suggest Team Camaro for help with most modifications. There are a lot more people changing out parts on that site. Just a suggestion if you don't get some quick answers here...

Are your front discs aftermarket? If so, it's a good idea to use the same brand front & rear. Most conversions require a min. 15" rim w/min. backspacing requirements specified by the manufacturer. Some would argue its a better investment to increase the size of your front disc's vs install disc's on the rear.
